Aviatrix3D Toolkit is a pure retained-mode Java scene graph API built on top of Java OpenGL bindings (currently JOGL, but will move to the formal JSR 231 bindings when released). Scene graphs, as high-level code structures need to be optimized for a particular field of graphics. While there are quite a number of gaming-oriented scene graphs already available, this toolkit is specifically focused on the needs of the data visualisation market - starting from a PC and working upwards to rendering clusters, CAVEs, Domes, HMDs etc. The beta 2 is stable and contains all the core features that will be part of the 1.0 release.
